The article reports a method of making dried larval specimens of Erythraeidae,ectoparasitism of insect,refreshed for taxonomic study.The dried larvae are let in cuvettes with 50％ ethanol.The cuvette plat is then put into a beaker with water in appropriate amount,fulling to 1/3-2/3 high of the cuvette plat.The beaker is heated until the water boiling,and then stop to heat.After that,the treated larvae are immersed into a container with ethanol-glycerol solution (50％ ethanol:glycerol =20:1),and then the container is warmed in a Water-Bath at 60℃ for 2h to ‘ refresh’ the larvae.The refreshed larvae are as mollescent as fresh ones and easy to be prepared for morphologic observation and long-term preservation.
